Tech writer (and hacking victim) Mat Honan says the password is dead.

Advice from the programmer and venture capitalist, including the biggest mistakes you need to avoid. "Ask yourself: who wants this right now? Who wants this so much that they'll use it even when it's a crappy version made by a two-person start-up they've never heard of? If you can't answer that, the idea is probably bad".

The Fore people of Papua New Guinea used to suffer from a mysterious "laughing death" disease they called kuru.
